Cats get this condition!

The exact underlying cause is unknown, however it is suspected to be an allergic response. The main allergens suggested are environmental allergens, food, or insect bites.

Rodent ulcers specifically cause enlargement of the upper lip, often with ๐ฎ๐ฅ๐œ๐ž๐ซ๐š๐ญ๐ข๐จ๐ง (loss of the surface layers of the skin). Thankfully, these lesions arenโ€™t painful for the cat, but they do make them look rather silly!

These lesions are fairly classic, so most of the time the veterinarian can diagnose them just by looking at them. However, there is a small chance that they might be a ๐ง๐ž๐จ๐ฉ๐ฅ๐š๐ฌ๐ข๐š (tumour), so usually a ๐›๐ข๐จ๐ฉ๐ฌ๐ฒ (taking a section of tissue) is recommended.

Typically this condition is managed by removing the allergenic triggerโ€ฆ if you can identify it! There is some research to suggest that flea bites might be the most common inciting cause, so usually these patients receive a long-term flea treatment. If the allergen cannot be identified and removed, then ๐ฌ๐ญ๐ž๐ซ๐จ๐ข๐๐ฌ to suppress the immune system may be used in some cases.
